Development and improvement effectiveness of sand compaction pile
The sand compaction pile method (hereinafter abbreviated as the SCP method) is a method for improving soft grounds by means of installing well-compacted sand piles in the ground. is a method to densify the target ground by pumping and injecting fluidized sand into the ground through a small-sized equipment. A mixture of sand and aVibro compaction allows economic spread footings with acceptable settlements and design bearing pressures generally in the range of 5 ksf up to 10 ksf. The process also reduces the seismic liquefaction potential. The required treatment depth is designed for each project, typically 15 to 50 feet, with a maximum depth of 120 feet.Vibro compaction Keller North America

Dynamic Ground Response during Vibratory Sheet Pile Driving
When the sheet pile is vibrated at the resonance frequency of the vibrator–sheet pile–soil system (system resonance), ground vibrations increase significantly and sheet pile penetration speed decreases. It is concluded that the vibration frequency is an important parameter for the efficient and environmentally safe installation of sheet piles.Either bottom feed stone column equipment or sand compaction pile equipment can be used to construct sand piles [1]. For this reasons the SCP method was selected for performing theoretical analysis required for improving the foundation soils under the high embankment. In order to apply the SCP method forSand Compaction Piles (SCP) for Improving Embankment

Performance evaluation of gravel impact compaction piers
For the design of gravel and sand compaction piles, four methods as A, B, C, and D are used, depending on the geotechnical characteristics of the soil layers. Methods B and C assume that no soil swelling occurs during the installation of sand compact piles (Kitazume 2005). The design method used in this article is somewhat similar to -type equipment, and shallow compaction by vibratory plate. Results of the compaction processes are presented and discussed to provide lower layer of medium to very dense sand (i.e.,-5.5 m). Compaction piles spacing are generally in the range of 2 m to 3.2 m (5 to 8 pile diameters).

Compaction at the middle of total depth is maximum and is decreasing to outwards from middle. To get better compaction at lower portion of pile, it is needed to increase number of blows or to enlarge pile depth. References: [1] Aboshi, H. and Suematsu, N.
